Caused by increased pressure altitude or a blocked airway. Can be thought of as not enough oxygen being able to enter into the lungs. This is the most common occurrence of hypoxia in aviation.
Caused by blood not being able to take up oxygen and transport it. Carbon monoxide poisoning is an example of this. The hemoglobin in your body will bind to the Carbon Monoxide instead of oxygen, and therefore transport it instead.
Caused by the circulatory system not being able to circulate enough oxygenated blood throughout the body. This could be caused by high g maneuvers in airplanes, where the body can't push oxygenated blood into the brain.
Additionally, stagnant hypoxia can be caused by diseases like sickle cell anemia, or hypothermia, which causes blood vessels to constrict.
Caused by cells not being able to use the oxygen that is transported to it. This can often times be caused by the use of alcohol or drugs which impair cell functions in accepting oxygen.
The best example of this would be cyanide poisoning, which directly prevents cells from using oxygen and is fatal.

| Conditions | LIFR | IFR | MVFR | VFR |
|---|---|---|---|---|
| Ceiling | less than 500 ft | 500 ft to less than 1,000 ft | 1,000 to 3,000 ft | greater than 3,000 ft |

"Night" means the time between the end of evening civil twilight and the beginning of morning civil twilight, as published in the Air Almanac, converted to local time.
This is when you can begin to log night time
Night takeoff and landing currency is based on takeoffs and landings that occur 1 hour after sunset to 1 hour before sunrise
Because of this, you could land during the "night" and have that landing not count towards your currency
